Scientists have used microneedle arrays to store a live vaccine at room temperature, and a...

While it’s vitally important to bring vaccines for diseases such as tuberculosis to developing nations, getting them there is only part of the challenge. Because these countries often have unreliable infrastructures, it’s entirely possible that the vaccines can’t consistently be kept as cold as is required. As a result, they could be rendered ineffective. Now, however, scientists from King’s College London have succeeded in containing a dried live vaccine in a microneedle array, that doesn’t need to be refrigerated.  Read More

A implantable material made from a blend of plastics has been developed to regrow damaged ...

Over the past several years, a number of research institutes have been exploring the use of implants made from material with a scaffolding-like structure, as a means of regrowing bone at severe injury sites. Both MIT and Tufts University, for instance, have been working on collagen-based materials. Now, England’s University of Southampton has announced the development of a new type of bone-growing substance, made from plastic.  Read More

The SIRT3 protein molecule that appears to play a central role in regulating aging and lon...

The quest for longer and healthier life, if not immortality, has been part of the human experience since we evolved the ability to recognize the total annihilation of individual death. Our understanding of the biology of aging at the molecular level is advancing so rapidly that it appears inevitable that another decade or two of life will be enabled before long. A new step in what may be the right direction has just been published by researchers at the University of California, Berkeley.  Read More

Students at Cornell University’s College of Veterinary Medicine can train in a simulation ...

Medical students have been honing their skills on human simulations for years and Cornell University’s College of Veterinary Medicine has been using the world's first robotic dog simulator Robo-Jerry II and Robo-Fluffy, his feline counterpart, to give aspiring vets experience since 2010. The robo-pets now have a new home in the form of a new robotic simulation center the University claims is the first of its kind in the world, with work underway on a more advanced robotic dog called "Butch" that will boast more realistic features and which will run on cheap, standard components.  Read More

The Infrascanner Model 2000 is a handheld device that uses near infra-red light to detect ...

A little over two years ago, we looked at a hand-held device known as the Infrascanner Model 1000, which uses near infra-red light to detect traumatic brain injuries. Now, the InfraScan company has received US Food and Drug Administration approval to market the 1000’s improved successor, the Infrascanner Model 2000.  Read More

Better understanding the structure of the humulone molecule found in hops could lead to mo...

A beer a day might not keep the doctor away but hops, one of the basic ingredients in beer brewing, could be good for you. In a development that could lead to better drug treatments of diabetes and cancer, University of Washington research associate professor of chemistry, Werner Kaminsky, has determined the exact structure of humulones and their derivatives – the acids in hops that give beer its distinctive bitter taste.  Read More

An existing robotic arm, which could be adapted for use in GE's system

Presently, when an operation is going to be performed at a hospital, people first locate all the instruments that the surgeon will require, inspect them, arrange them on a tray, sterilize them, and then deliver them to the operating room. According to General Electric’s GE Global Research division, however, robots could do all of those things better. To that end, the group has recently partnered with GE Healthcare and the U.S. Department of Veteran’s Affairs, in a US$2.5 million two-year project to develop just such robots.  Read More

RP-VITA in action

iRobot has announced that its RP-VITA autonomous remote presence robot, co-developed by InTouch Health, has received clearance from the U.S. Food and Drug Administration (FDA) for use in hospitals.  Read More

A conceptual image of the vaccine patch developed at MIT that could enable the use of DNA ...

Taking a two-month-old in for vaccination shots and watching them get stuck with six needles in rapid succession can be painful for child and parent alike. If the work of an MIT team of researchers pans out, those needles may be thing of the past thanks to a new dissolvable polymer film that allows the vaccination needle to be replaced with a patch. This development will not only make vaccinations less harrowing, but also allow for developing and delivering vaccines for diseases too dangerous for conventional techniques.  Read More

Blue light has been used to kill potentially-lethal Pseudomonas aeruginosa bacteria (pictu...

Over the past few years, blue light has allowed us to understand heart problems, control brain functions, and activate muscle tissue. Now, another biomedical function can be added to its list – because it’s known to have antimicrobial qualities, it’s been used to stop infections of the skin and soft tissues.  Read More
